This research seeks to investigate the viability of using Tectona grandis wood powder as a reinforcement material in polymer matrix composites because increasing awareness natural fibers that offer impressive characteristics and cost-effectiveness addition being biodegradable. The were mixed with epoxy resin, mixture was passed through filter remove fiber bundles then compression molded form composites, which cured an oven. Different experiments performed on composite measure its mechanical characteristics. tests tensile test properties like strength elastic properties, for evaluating behavior under compressive load, hardness rate indentation resistivity, impact material's ability withstand shock loads. results showed caused significant enhancement aspect composite, where obtained 249.83 MPa, 17.98 MPa. SEM microstructural analysis moisture absorption performed, while additional carried out Ansys work bench software. proves improves represents viable substitute synthetic reinforcements.

PLA Reinforced with Limestone Waste: A Way to Sustainable Polymer Composites

Polymers, Год журнала: 2025, Номер 17(5), С. 662 - 662

Waste stone sludge generated by the extractive industry has traditionally posed significant disposal challenges. This study redefines as a valuable raw material incorporating it into polylactic acid (PLA) to create sustainable composite materials. Pellets and filaments composed of up 50% weight limestone powder PLA were successfully produced using melt blending in twin-screw extruder. Scanning electron microscopy (SEM), X-ray fluorescence (XRF), diffraction (XRD) analyses revealed uniform distribution particles within matrix confirmed chemical structural compatibility components. Thermogravimetric analysis (TGA) showed that composites retained thermal stability, while mechanical testing demonstrated enhancements stiffness, with an increase elastic modulus for containing powder. The flow rate (MFR) decreases increasing filler content. brittleness also increased, reducing impact resistance. Mechanical tests performed on injected 3D-printed specimens. filament was used 3D printing, small XYZ calibration cube.
